Juniper Networks ERX Hardware 8 - Manual (Page 59)

Installing Modules
WARNING: Be sure circuit breakers for the power source are in the OFF position
before attaching power cables.
WARNING: Remove jewelry (including rings, necklaces, and watches) before
working on equipment that is connected to power lines. Metal objects heat up
when connected to power and ground and can cause serious burns or become
welded to the terminals.
WARNING: Do not insert any metal object, such as a screwdriver, into an open slot
or the backplane. Doing so can cause electric shock and serious burns.
WARNING: Never attempt to repair parts of modules yourself. Only trained
customer service personnel are authorized to service parts. Call Juniper Networks
Customer Service to make arrangements to return defective modules for repair.
Installing SRP I/O and SRP Modules
You must install SRP modules in specific slots in each router. See
Table 5 for SRP module slot assignments.
Table 5: SRP Module Slot Assignments
Router Slot
ERX-14xx models 6 and 7
ERX-7xx models 0 and 1
ERX-310 router 0
NOTE: Because of different physical dimensions and switch fabric capabilities, SRP
modules are not interchangeable between systems. For example, the 10-Gbps SRP
module used in ERX-7xx and ERX-14xx models cannot be used in an ERX-310
router, and vice versa.
